I thought I would share how I installed MEDUSA4 Personal 5.1.2 on openSUSE 12.3 x86_64.

After a standard openSUSE 12.3 64bit installation, I added the following 32bit environment to prepare the required Medusa installation and runtime environment (RTE) . These packages can be added as root with zypper commands in a terminal as shown below, or with the YaST2 gui package manager. The last zypper command is on one single command line.
